RAIL ATTACHMENT TO PREVENT SPREADING.

Application filed June 26, 1922.

To all whom it may concern:

Be it known that I, ARTHUR L. PoLLooK, a citizen of the United States, residing at Kingman, in the county of Mohave and State of Arizona, have invented certain new and useful Improvements in a Hail Attachment to Prevent Spreading, of which the following is a specification.

This invention relates to railway appliances, and more specifically to an improved rail-attachment to prevent crawling and spreading.

One object of this invention is to provide a simple, easily attached, comparatively inexpensive and thoroughly practical and. eflicient means to prevent creeping or crawling and spreading of railway rails.

Other objects and advantages will be pointed out or implied in the following details of description, in'connection with the accompanying drawings in which Figure 1 is a plan of a partof a railway having my improved antispreadiug device applied thereto. v

Figure 2 is a side elevation of the structure illustrated in Figure 1. v

Figure 3 is a view, partly in full elevation and partly insection, of my improved rail attachment detached.

Figure 4 is a View somewhat similar to Figure 2, but illustrating a modified form of the attachment, the same partly being in vertical section.

Figure 5 is a detail View of a detached end of one of the antispreading bars illustrated in Figure 4.

Figure 6 is a cross-sectional view of the form shown in Figs. 1 and 2, taken adjacent one of the rail ends.

Referring to these drawings in detail. in which similar reference characters correspond with similar parts throughout the several views, and in which the rails, ties, fish-plates, bolts and spikes are of ordinary construction; the invention consists in the combination of the above-named parts in connection with the antispreading. attachment which will presently be described in detail.

Two ordinary railway rails 6 are seated on and secured to ties 7, and fish-plates 8 are secured to the rails by means of bolts 9, so as to secure the ends of the rails together in a well known manner. The fish- Serial No. 570,989. 1

plates or angle bars 8 may be of the type or trated in Figure 3, is preferably formed of bar-iron about three inches wide, one-half inch thick and 12 to 18 ft. long. The middle portion 11 of this bar is narrowed to approximately one and one-half inches and provided with notches or openings 12 which receive the bolts 9 when the bar 10 is in its attached position that is,-when it is seated on the ties 7, either between or outside .of the rails, and has its middle portion 11 between the rail-ends and one of the fishplates 8. At opposite endsof the narrowed middle portion 11, the portions 13 of the bar 10 have their sides standing vertically, but being inclined or diagonal to the length. of the rails 6. At 14: the bar 10 istwisted through an angle of 90?, at15 it is downwardly inclinedand from 16 to the ends of the bar 10, itis substantially level or horizontal. This horizontal portion is indicated at 17 and is provided with openings 18 for receiving spikes 19 and thereby securing the diagonal end portions of the bar .10 to the ties on which these portions 17 rest.

By referring again to Fig. 1, it will be seen that all parts of the bar 17 are disposed diagonally to the rails 6, except the narrow middle portion 11; and therefore, and because it is secured to the ties, this bar 10 combines with the rails (3, the ties 7, and the ground (not shown, in which the ties are embedded in the usual manner), to

form a truss or truss-like structure which efiectually prevents longitudinal movement of the rails, also lateral movement of the rails 6 at their meeting ends'and at all points laterally opposite to the bar 10.

Referring to the modified form in Figures l and 5, it will be seen that two bars 10 are provided, and that these bars have outer end portions 17 similar in construction and arrangement to the part 17 previously described; but instead of the notches 12, other openings or holes 12 and 12 are provided in the inner end of each bar 10. This form of brace or truss-bar can be advantageously applied to the outer surface of one of the fish-plates 8 without removing the fishplates. This may be done by removing end bolts 9, loosening the nuts on the intermediate bolts, hooking the ends of the bars 10 over these intermediate bolts, replacing the end bolts with longer ones, then replacing the intermediate bolts with longer ones. Another way to attach the bars 10 is to remove two bolts from one side of the center of the fish-plate, place one of the bars 10 and secure it by appropriate bolts, then remove the other two bolts from the fishplates and attach the other bar l0 by appropriate bolts. In this latter way, especially, the fish-plates are held rigidly in place during the entire operation of attaching the braces or bars 1.

It is to be understood that while the bars 10 and 10 provide for securing their ends 17 to not more than three ties, it is intended that they be extended so as to be secured to five or more ties; but are so illustrated for the lack of sufiicient space.

It is not intended to limit this invention to the exact details of construction and arrangement as illustrated, but changes may be made within the scope of the inventive ideas as implied and claimed.

hat I claim as my invention is:

l. A rail anchor comprising a bar hav ing angularly disposed end portions adapted to be secured to the ties and a substantially vertical intermediate portion adapted to occupy a position adjacent the web of the rail, a portion of said vertical intermediate portion being reduced and provided with notches adapted to be engaged by the bolts which secure the fish plate to the rails.

2. The combination of two railway rails, ties on which said rails are secured, fishplates on opposite sides of said rails, bolts through said rails and fish-plates, and a bar having openings therein and being seated between said rails and one of said fish-plates, said bolts extending through said openings, said bar extending diagonally from said rails onto a plurality of said ties and secured thereto, for the purpose specified.

3. The combination of two railway rails, ties on which said rails are secured, fishplates on opposite sides of said rails, bolts through said rails and fish-plates, and a bar having openings therein and being seated between said rails and one of said fish-plates, said bolts extending through said openings, said bar having both end portions extending diagonally from said rails onto a plurality of said ties and secured thereto, for the purpose specified.

4;. The combination of two railway rails, ties on which said rails are secured, fishplates on opposite sides oif said rails, bolts through said rails and fish-plates, and a bar provided with a reduced central portion having openings therein and being seated between said rails and one oif said fish-plates, said bolts extending through said openings, said bar extending diagonally from said rails onto a plurality of said ties and secured thereto, for the purpose specified.

In testimony whereof, I affix my signature.

ARTHUR L. POLLOCK.
